Greetings there. Maybe someone can help me with my NSMatrix troubles.

I have a NSMatrix of checkboxes. I wanted to use the tag of each checkbox to know what to modify when they were clicked, and assigned to each one of the cells' target an action (which is the same for all of them). However, when I run the program, the sender of the action that is performed when I click on one of the checkboxes isn't the button cell, but the NSMatrix, so I can't just use [sender tag] to know what to do (that action can also be called from menu items, so I wanted to avoid type-checking)

Is that a bug of a feature? I figured a matrix cell would send itself as the sender of an action if set to have one, but I might be wrong. And if the NSMatrix is meant to be the sender, it makes for not very elegant code.

Any good advice on how to keep the code the same for menus & checkboxes and avoid having these problems will be greatly > appreciated.

IIRC, the solution is to:
- set the action from the NSMatrix to the target
- in the method:

- (void) someoneClickedOnOneOfMyCheckBoxes:(id) sender
{
int tag;

tag=[[sender selectedCell] tag];

// Do your process here
}
